stdio.h

Hello. I am trying to read and write integers to a file using the getw() and putw() using the stdio.h. However each time I use these functions I get an error: no reference to putw() or getw(). How can I add these functions to stdio.h or are there other functions I can use to write integers to files. I am using MCUXpresso v11

Are you using a semihosting library? For example:

Otherwise: I wrote recently about that topic here: https://mcuoneclipse.com/2022/01/25/semihosting-with-nxp-mcuxpresso-sdk-and-frdm-ke02z/

I hope this helps,
